Looking at NewEggs web site, I see a couple of things:
The PNY has DVI output, the VT doesnt. Plus for PNY
The PNY has what looks like the nVidia reference HS/Fan which I find to be way too noisy. The VT has a different type of fan. If it is quiet, I'd say Plus for VT
The PNY is $159. The VT is $185. I think PNY wins
